The present invention relates to an auto- MAT'IG EMPTYING onBECEPTAC'LES CONTAINING A LIQUID AT A GIVEN TEMPERATURE 1 maticapparatus for emptying liquids contained in receptacles of any kind whenthe outside atmosphere or air. attains a given temperature, and may beadvantageously used for the automatic emptying of the water contained inthe cooling chambers of internal combustion engines.

The apparatus embodying the present invention is characterized by thecombination of a device of temperature, and a ceptacle can be emptied.

In this combination,

which is'deformable'oby'the effect valve by which the re the'said devicewhich is deformable by the elfect of the temperature variations isitself characterized by the fact that it consists of a pluralityofsections;

each of which sections forms ure whereof one part 001131 a geometricfig-,

sts of a metal member such as steel having a relatively smallcoeflicient of expansion and which, in

the normal conditions of operating, is not mechanically deformable 1n agiven direction, whilst the part ending at the two extremities of thefirst mentioned'part is constituted by metal pieces or stance of alumlnum, having coefiicient of expans1on, and 1 conditions these members are'directlon. The said deformable in a given members, for ina'relativelyhigh n the operating mechanically sections are placed end to end, in thesaid direction and are joined together. One of the sections at the endof the series is secured to a fixed point, and the section at the otherend acts upon a lever by which the operating means may be actu Suchapparatus may be structed, and for instance, an

emptying valve ated.

variously conapparatus may i be employed in which the emptylng valve ofthe receptacle comprises a valve normally closed by'a spring, andcomprising a controlling stem or rod secured to apivoted counter;

weight combined with a camrnormally resting upon one end belng sodlsposed of the said lever,-,the whole that the said leverwill releasethe said cam when the proper temperature is attained; the cam thusweight and. causes falls by its own the descent of the saidcounterweight, thereby opening the valve.

The accompanying drawin gs show an emsemi No.j409,736, and in GermanyAugust 15, 1928.

bodiment of the invention, whichisnot of a limitative nature. i

Fig. l is a longitudinal axial section of, a device for the automaticemptying of a receptacle, accordingto thev invention.

Fig. 2 is a plan viewof the same, Fig. 3 is anelevation of one end ofthe apparatus shown in Fig. 1, and

Fig. 4 is a similar View of the other end of the apparatus.

In these figures, like numerals represent corresponding parts.

The apparatus .herein represented comprises a frame consisting of twoplates 1 connected togethergby cross-pieces 2, 2, 2"etc.

One cross-piece 2 carries the devicewhich is deformable by heat. Thisforms a thermostatlcdevice which herein consists of a plurantypf.sections assembled in a consecutive series.

Each section of said thermostatic device ,member 3, said membe rs 4-consisting of a metal or alloy such as aluminum whose coefficient ofexpansion exceeds that of the member 3.

As shown in Figures 1 and 2, the deform able sections are preferablycombined in pairs, and in each pair thus formed, a rigid member dispreferably combined with said deformable members which form a sortoflozenge-shaped section of which the said indeformable member 3 .is oneof the onals. A I

In the construction shown, four such lozenge-shapedv sections may be'mounted in a series on the axis ww, and this deviceis secured at oneend 8 to the cross-piece 2; the

diag-- to assure the indeformability temperature, and it acts upon alever which turns on an axle 11 and is provided with an end portion 12normally in contact with a cam 13 which is movable on an axle 14 andsupports a counterweight 15, movable on an axle l6. Herein, the saidcounterweight 15 has the form of a tube containing a heavy mass which isloose in said tube and" which may consist of metal ic grains, or of aball, or the like. 7

f A lever 18 secured tothe shaft lticontrols the stem 19 of the valve 20which is provided with a closing spring 21 and is mounted on theemptying pipe 22, 23 (not shown); to be emptied. v

The saidapparatus is so arrangedtha-t when the thermostat is cooled to adeter mined temperature, which is below the normal temperature, thecontraction, of the said deformable arrangement comprised between theelements 8 and 9 is sufficient to turn} the lever 10 through an anglesuch that the end 12 will be separated from the cam 13. Since the saidcam is no longer supported, it will a fall while turning on its axle 14;the counterweight 15 then falls. Thejmass 17' which is loose in the tube15 moves from one end of the said, tube to the other. The valve 20 whichismoved from left to right now opens, and the receptacle connected tothe pipe 22', 23 is thus emptied.

When the temperature has resumed its normal value, the apparatus maybeplaced by'hand'i'n its initial position, and it is then enabled to actagain.

As shown in Figures 1 and 4, the lever 10 is provided with an adjustingdevice, and this device consists of a screwthreaded rod 24 which issecured to the thermostat and traverses the said lever, and also of aspring 25 mounted between the thermostat and the lever, and of a nut26screwed upon the said rod and provided with a hand wheel 27.

As shown further in the drawings, the

" emptying. valves of four distinct receptacles sented is adapted toactare mounted on the emptying pipes 23, 23', 23", 23 of the saidreceptacles, and all of the said valves are controlled by the samethermostat. In this event, the counterweight may consist of severaltubes, for in stance, two tubes 15, 1'5 4:).

A common funnel 28 maybe disposed below these various emptying pipes.
